Effect of glucocorticoids and thyroid hormones on NHE3 mRNA abundance. A: Northern blot with 15 μg of total RNA from renal cortex of rats of ages. B: β-actin mRNA was shown for comparison. NHE3 mRNA abundance was significantly less in the 9-day-old (9 d) and ADX-hypothyroid (adx-hypoT) groups than that of the other groups (P < 0.05). There were at least 4 measurements in each group. cort, Corticosterone; T4, thyroxine.
